Explanation
- Operation at compensation start-up and cancellation
Unlike tool side compensation the operation performed at leading edge
compensation start-up and cancellation does not vary. When G41.3 is
specified, the tool is moved by the amount of compensation (V
C
) in the
plane formed by the movement vector (V
M
) of the block after a G41.3
block and the tool vector (V
T
) obtained at the time of G41.3
specification. The tool movement is perpendicular to the tool vector.
When G40 is specified, the tool is moved to cancel VC. The following
illustrates how the compensation is performed.

- Operation in the compensation mode
The tool center moves so that a compensation vector (V
C
)
perpendicular to the tool vector (V
T
) is created in the plane formed by
the tool vector (V
T
) at the end point of each block and the movement
vector (V
M
) of the next block.
